Abstract: Disclosed is an image reading apparatus which reads a document placed on a reading unit including a display input unit including a first display unit which displays information and an input unit to accept an input operation with respect to the first display unit; a document holder which sandwiches the document with the reading unit, a support which supports the document holder so as to rotate so that a facing state of the document holder with respect to the reading unit is switchable and a second display unit which includes a surface of the document holder which faces the reading unit and the second display unit carries out a display in the surface.

Abstract: An image forming apparatus capable of communicating with an electronic pen at least includes a communication section for obtaining, from the electronic pen, electronic pen data including multiple pieces of position information obtained by detecting a position detection mark printed on a hand-writing sheet by the use of the electronic pen; a language analysis section for analyzing the electronic pen data, identifies one or more hand-written images defined by the multiple pieces of position information, and creates intermediate data that defines the arrangement of objects including respective hand-written images; an image processing section for rasterizing the intermediate data to create bitmap data; and a printing section for conducting printing based on the bitmap data.

Abstract: An image forming apparatus including an image acquisition section which acquires a color image; a memory section which stores a first table correlating a specific color with a symbol indicating the specific color; a color discrimination section which discriminates a color on the basis of color information of each portion in the color image, and extracts an area having the specific color; a symbol composition section which specifies the symbol corresponding to the specific color by reference to the first table, and composes the specified symbol into the area having the specific color in the color image to generate a composite color image; and an image output section which outputs the composite color image.

Abstract: An image forming apparatus includes a transferring device equipped with an endless rotating member for transferring a recording sheet while holding the recording sheet on a surface of the rotating member by rotating the rotating member. This transferring device has a first position, a second position and a third position in this order along a rotation path of the rotating member.

Abstract: An image forming apparatus which includes an electrophotographic copying machine operable to form an image on a recording paper and a laser printer operable to form an image on a recording paper independently of the copying machine. The copying machine includes a paper feeder from which the recording papers are selectively supplied to an electrophotographic image forming station in the copying machine and to a paper supply unit in the laser printer. The image forming apparatus also includes a paper recirculating unit operable at a specific timing to replenish the recording paper, supplied from the paper feeder, onto the paper supply unit in the laser printer.

Abstract: The improvement of a complex machine comprises a host computer, a duplicator, a laser printer, and a sheet supply unit. In a first sheet supply mode a sheet is supplied from the sheet supply unit to the duplicator; and in a second sheet supply mode a sheet is supplied from the sheet supply unit to the printer. The complex machine further comprises sheet transfer mode selecting means for selecting one of an interruption mode wherein the sheet supply mode currently set up is interrupted to proceed to a selected sheet supply mode, a wait mode wherein the selected sheet supply mode is effected after completing the process of the sheet supply mode currently set, and a rejection mode wherein proceeding to the selected sheet supply mode is rejected when either one of the first and second sheet supply modes is currently set up and the other one of the two sheet supply modes is selected concurrently.

Abstract: An image forming apparatus is provided with a host computer, a copier, and a printer operable in response to instructions from the host computer. Upon receipt of image information from the host computer, the printer forms an image on a first sheet whereas the copier forms on a second sheet an image of a document placed on a document platform. The apparatus is further provided with a document conveying device for conveying to the document platform the first sheet as a document on which the image has been formed by the printer. The apparatus has at least two drive modes: a single drive mode at which all the transcripts are prepared by sole use of the printer and a double drive mode at which the first sheet having the image formed by the printer is conveyed by the document conveying device so that the rest of transcripts are prepared by the copier.

Abstract: An image forming apparatus having a developing device wherein a developing material of a toner and a magnetic carrier is circularly transported from a toner supply portion to a developing region formed between the developing device and a photosensitive member while mixing the developing material. The developing device is provided with a sensor for detecting a toner density of the circulating developing material at a specified detection position in the developing device, and the toner is supplied from the supply portion to the developing material at the specified detection position and to the developing material at a minimum of one position other than the detection position when the detected toner density of the developing material is less than a predetermined standard density.
